NEW QUESTION 29
A storage administrator is required to test a new version of an application loaded on a secondary host. The administrator must use existing data contained on a LUN provisioned from Unity to a primary host.
Which solution will meet the requirement and provide space efficiency?
- A. Create an Asynchronous Replication on session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host - B. Create a snapshot of the LUN
Configure LUN access for the secondary host
Attach the snapshot to the secondary host - C. Create a snapshot of the LUN
Configure snapshot access to the LUN for the secondary host
Attach the snapshot to the secondary host - D. Create a Synchronous Replication session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host
Answer: C
Explanation:
Explanation/Reference:
Explanation:
Attaching a snapshot is only applicable for block snapshots, and makes the snapshot available for host IO. A host must have Snapshot access or LUN and Snapshot access configured in order to access the snapshot.
When a snapshot is attached, Unisphere provides the option to create a copy of the snapshot in case the administrator wants to preserve the current snapshot view for future use.

NEW QUESTION 31
How is encryption set for a Unity storage system?
- A. Automatically set at the factory
- B. First time the license is applied
- C. Clicking the "Mode" checkbox on the Manage Encryption page
- D. Selecting "Status" on the Manage Encryption page
Answer: B
Explanation:
Explanation/Reference:
D@RE is included by default on Unity arrays and included in the Unity license file unless otherwise requested during ordering. Therefore, all that is needed to activate D@RE is to install the D@RE enabled license file. The license installation process is not specific to D@RE, and is required to be performed before using the array. When logging into Unisphere for the first time, license installation appears as a step of the Unisphere Configuration Wizard, prompting the administrator to install the license file obtained from EMC. If this license file includes D@RE functionality, D@RE will be enabled once the license file is installed successfully
Note: Unity storage systems address sensitive data concerns through controller-based Data at Rest Encryption (D@RE), which encrypts stored data as it is written to disk.
D@RE is a license controlled feature available by default on Unity storage systems, and, being designed to be largely invisible to administrative end users, requires almost no effort to enable or manage. Enabling the feature or backing up the encryption keys externally takes just seconds, and redundant keystore backups stored on array ensure that user data is always as available as it is secure.
